Equivalent Series Resistance (ESR) Meters

Thanks for review. Very good 👍❤

Thanks for watching!

Can you do a comparison between Antek blue ear vs this one ? How close are the readings ( out of circuit & in circuit )

[@StuartPatterson]

That is a great idea but I don’t currently own the Anatek Blue ESR meter. If that changes in the future I will certainly compare them.

I've found that the DER DE-5000 LCR meter is a much better choice than the GME in that price range. I've had great success with it, and its in-circuit ESR performance is quite good. A recommended improvement for the DER is to make your own Kelvin test clips for the unit. A good test for it was a subwoofer amp that had 12 out of its 16 electrolytics gone to the dark side. All 12 read bad both in-circuit and out-of-circuit. Accurate in-circuit ESR testing is extremely useful. The unit is also excellent for testing inductors, and of course resistors. One MUST DISCHARGE THE CAP first. Beyond safety for the unit, a small charge left on a cap can confuse an ESR/C meter.

Thanks! I need to checkout the DE-5000. The price is certainly good!

[@matambale]

@@StuartPatterson Your certainly welcome, and thanks for this video. Just wanted to add a note that there are a few videos on YT about how to fashion your own Kelvin clips for the DE-5000. It's worth the effort and additional expense for the additional accuracy and convenience.

[@StuartPatterson]

@@matambale OK, I will certainly check them out!

I have seen a video that the TC1 type meters need to be calibrated before use.have you done that?

[@StuartPatterson]

Good question. I have never calibrated one before and have not looked inside one to see how it could be done. Maybe I should.

[@Byzmax]

Useful demonstration.

[@StuartPatterson]

Thank you!

Are ceramic capacitors treated any differently than electrolytic caps as far as testing ESR?

[@StuartPatterson]

It is my understanding that ceramic caps can still suffer from issues with ESR but it is extremely rare when compared to electrolytics.

[@jonathanguepe1900]

Great video - question. How did you fix your MESR-100 tester when you tested a charged cap? I just did it and it's not working now. Any help would be appreciated. Thanks.

[@StuartPatterson]

I replaced a diode that had blown. Let me know if you can't figure out which one and I will open my meter and look, maybe it will jog my memory. I think it was pretty obvious in my case.

[@guateque1718]

I have the same issue. A cap damaged it.

[@fritzj6803]

Great tutorial. You can also test the resistance and microhenries of the inductors with the esr meter. The reactance formula is 2𝛑FL. That would be 2 x 3.14i x frequency of esr meter x 100 (uH) Just plug it in. R=0.628 X L(uH) L(uH)=R(ohms)/0.628

[@StuartPatterson]

Thanks!

[@DrN007]

Interesting how the the 3rd one is obviously subpar to MESR, and yet more than twice the price... Who would pay for that?!?

[@StuartPatterson]

Always better to research test equipment before buying it!

[@DrN007]

@@StuartPatterson Even $50 is too much for something relatively simple. I think it's priced as such only because it's much less in demand than DMMs, hence less competition.

@@DrN007 Makes sense. Love your username!
